Pipe



Fig. 6 shows a sectional view of a portion of a pipe showing a: modification of the invention.

In considering the drawing in more detail, Figure 1 shows a smoking pipe having a hollow bowl and a stem 2. The pipe may be made of any suitable material ordinarily used in the manufacture of pipes such as briars, wood fibers molded with synthetic resinous binders, or the like. A longitudinally extending recess or groove-shaped portion extends from the base or bottom of the bowl forwardly along the lower exterior surface of the stem 2, and is so shaped as to form a guiding channel 3 having flanges or retaining edges 3a, for the spring element 4. The retaining edges of the guiding channel serve to retain within the boundaries of the channel that portion of the flexible spring which is in the channel. A flexible spring element 4 is inserted in slidable engagement in the guiding channel 3 and is adapted to be moved back and forth in the channel through the medium of the operating knob 5 which may be an integral part of-or fastened to the flexible spring element by means of any conventional securing means 6 such as rivets or anchoring pins.

The guiding channel may be cut or molded directly into the material from which the pipe is manufactured or a guiding channel manufactured from metal, molded rubber, synthetic resins or the like may be fastened to the lower exterior portion of the pipe stem or may be inserted into a recess or groove formed in the lower portion of the stem. The pre-formed insert type of guiding channel is the preferable construction as contrasted to the type which is cut or molded into the body of the pipe stem because of less wearing action between the actuating spring 4 and the walls of the guiding channel 3. It is, however, understood that any type of guiding channel may be used in connection with my invention as long as it functions as a guiding means for the spring element 4 and when the term guiding channel or guiding means is used herein and in the claims, a broad interpretation shall be applied to the term consistent with the disclosure contained in the specification.

The guiding channel 3, as illustrated in Figure 2, is a preformed insert type placed in a groove formed in the lowest portion of the stem and has the forward edge 1 reversely bent. The reversely bent edge projects into a small slot cut in the stem 2. As the pipe mouthpiece I 9 is pushed into the stem opening or flue, the guiding channel 3 is anchored securely into place. The other edge of the guiding channel is anchored by having the edge of the channel 3 projecting into a small slot as illustrated in Figure 2.

An ejector plate 8 is positioned in the pipe bowl and is fastened to the end of the flexible spring 4.

The nine bowl I, has an opening 9 in the bottom the eof. A closure and deflecting means H), whi h may be substantially L-shaped, having a slightlv curved surface ll, adapted to properly guide th flexible spring 4. is fitted into the opening 9. The opening is substantially sealed excentin sufiicient space is allowed between the substantially L-shaped closure and deflecting element and the pine stem at point I 2 to permit entrance of the flexible spring 4 into the pipe bowl I. Free and easy sliding access of the flexible spring into the pipe bowl is essential for the pro er operation of the ejector plate.

The ejector plate 8 may be a solid plate, preferably conforming to the shape of the bowl of the pipe and being substantially the same diameter pin i8.

as the lower portion of the pipe bowl. It will be clear, however, that the diameter of the plate should be slightly less than the diameter of the approximate mid-portion of the pipe bowl since the ejector plate should be free for easy and free movements when actuated by the flexible spring 4. If desired, the ejector plate may be perforated with holes l3, as illustrated in Figure 3. The perforations enable the user of the pipe to develop better draft during smoking of the pipe. Also, if desired a filter [4, such as a paper filter or equivalnt filters, may be used with the ejector plate and may be afiixed to the plate by fastening to the A filter paper I 4, as shown in Figure 4, may have radially extending slits l5 cut into the piper for more efiicient operation.

A bore or flue 16 extends through the stem 2 of the pipe and opens into the bowl l. The bore or flue mayv continue in a straight line as illustrated at I 6-1) in Figure 2 or in a modified form, the flue may extend into the pipe bowl at an angle greater than a right angle, the angle as illustrated at |6a in Figure 6 being measured at the approximate juncture point of the pipe bowl and the stem. If the stem flue continues as indicated at i 6b, the smoker may apply draft only from a point below the ejector plate; if, however, the pipe is; constructed to include the curved or angular flue construction feature as IB-a, drait may be applied to the tobacco charge from above or below the ejector plate, depending upon the smokers desire. As an illustration, if the flue construction Iii-a is used and the ejector plate is in the 'IOWBr portion of the pipe bowl, draft is applied to the charge from above the plate and the smoke will be relatively hot to the smoker. However, if the ejector plate is raised in the pipe bowl by means of the actuating spring 4 to a point above the flue opening, draft may be applied from below the plate and the smoke will be cooler as compared to the preceding example. In this manner the temperature and taste of the smoke which the smoker draws from the pipe can be controlled quite easily. Another desirable feature of the construction lG-a lies in the fact that the pipe may be easily cleaned since when a pipe cleaner is inserted into the bore or flue from the mouthpiece end of the pipe, the cleaner will curve upwardly into the pipe bowl as the cleaner reaches the curved or angular portion lG-a in the flue. This feature enables one to easily remove the pipe cleaner from the pipe bowl.

In using my pipe, the ejector plate is usually in the normal position as illustrated in Figure 2. When the ejector plate 8 is'in the normal position, the operating knob 5 of the flexible spring 4 is moved or slid along the guiding channel 3 by applying pressure to the operating knob and moving it back towards the pipe bowl. As the knob is moved in the direction of the pipe bowl, the flexible spring will be guided through the opening 9 in the bottom of the bowl and upward through the approximate middle of the bowl. Due to the slight curvature of the flexible spring, the edge of the ejector plate 8 may tend to scrape on the wall I! of the bowl, and, as the plate emerges from the top of the bowl as illustrated in Figure 1, the contents of the pipe will be emptied. Furthermore, through the scraping action of the plate on the side walls of the bowl, the pipe bowl will remain quite free and clean from excess charred residues or the like. Also, if a filter paper I 4 is used on the ejector plate 8, the paper will be automatically loosened from the plate by the edge of the pipe bowl as the ejectonplataris returnechth?theinormalipositionz Thei ejector isireturned as showniin :Ei'giu'axZ by'omerely 'lapplying: pres-s sure "to:ithacoperatinglknobza and moving:=the Y knob forward? toward: the: mouthpi'ecea: Tn; this actioni: therflexible aspring iawilli' movedownward througlrithelrpipe bowl and will then bei deflected by theivclos'ur'e and deflecting: means .-l into the spring steelfspring- WirQF'OI' any-" otherflexible' spring material": which maybe guidedi in chain'- nels 1 and defle'cted around severe or sharp *angles andsti-ll impart actuating for'c'e tothe means: to
